3U 4HP front panel blanking plate DIN41612 with PCB mounting hole
Introduction
I have originally designed front panels for few of my projects, but this turn out so well that I have now posted all schematic, gerber files and documentation to fellow enthusiast such as yourself. Perhaps (and I hope) content in this obscured corner of interwebs will inspire you to start your own projects.
This variation of blanking plates contain two holes to attach PCB holder and front handle, you might have to drill another hole so that handle is not turning. You can use these either side of these blanking plates. PCB's are made of aluminium and signle sided, black matt colour (or whatever color your PCB house offers) and brushed aluminium on the other. Blanking plates for your Microcomputer, Eurorack project or just blank those pesky holes in your favourite synth ᕕ(⌐■_■)ᕗ ♪♬
These boards look absolutely gorgeous in black solder mask if you going for that classy synth look.
I can advise you where to buy PCB rear mounting bracket, alternatively you can 3D print your own, files are all over interwebs.

... but if you feel like getting something for nothing isn't your cup of tea (completely understandable) (ಥ﹏ಥ) and a prefer to support me and get something back in return, then you can purchase directly on my eBay or Tindie shop. However if you are still up for an adventure */in very positive way/* (and are happy to have PCB's made yourself in your favourite PCB house - PCBWay is highly recommended), then carry on, download gerber files and have fun! ( ͡° ͜ʖ ͡°)

Assembly instructions and notes
■ Please be aware that gerbers are designed for 1 sided Aluminium PCB, please choose this option when ordering from your favourite PCB house (JLCPCB is recommended).
■ You can use these card in industry standard DIN41612 3U subrack / Eurorack.
■ Card has been designed to be very versatile and you can use it as blank or to mount PCB or other stuff to it. just use 2.50mm standard drill bit.
■ PCB's are usually 1.60mm, however standard DIN41612 is 2.50mm so bare this in mind for critical applications.
■ Blanking plates contain two holes to attach PCB holder and front handle, you might have to drill another hole so that handle is not turning.
